Description
Galvanisierte Bestecke aus gewöhnlichem Eisen oder Stahl haben den Mangel, daß der galvanische Niederschlag an den Spitzen und Aufliegestellen bald abgescheuert wird, so daß das blanke Eisen zutage tritt und rostet. Ganz besonders ist dies an den Löfifel- und Gabelspitzen der Fall; bei ersteren wird das Überzugsmetall durch die ständige Reibung der Löffelspitze auf dem Teller abgenutzt, bei letzteren beim Zerlegen der Speisen mit dem Messer abgeschnitten. Man hat diesem Übelstand dadurch abzuhelfen versucht, daß man den galvanischen Niederschlag an den gefährdeten Stellen verstärkte, allein die Abnutzung ist gerade an den Spitzen eine so große, daß trotz der Verstärkung des Überzugsmetalls nach einiger Zeit das Grundmetall freigelegt wird.Galvanized cutlery made of ordinary iron or steel has the defect that the galvanic precipitation on the tips and resting points is soon rubbed off, so that the bare iron comes to light and rusts. This is particularly true of the Löfifel and fork tips the case; in the case of the former, the coating metal is replaced by the constant friction The tip of the spoon on the plate is worn, in the case of the latter when cutting the food cut off with a knife. Attempts have been made to remedy this problem by that the galvanic precipitation was increased in the endangered areas, but the wear and tear is precisely on the Tips so large that after some time, despite the reinforcement of the coating metal the base metal is exposed.
Bei galvanisierten Bestecken mit Neusilberauflage ist diese teilweise Freilegung des Grundmetalls nahezu bedeutungslos, weil das Neusilber nicht korrodiert; bei Stahlbestecken aber rosten die freigelegten Stellen, wodurch die Bestecke in kurzer Zeit zerstört werden.In the case of galvanized cutlery with a nickel silver coating, this is partially uncovered Base metal almost insignificant because the German silver does not corrode; with steel cutlery but the exposed areas rust, whereby the cutlery is destroyed in a short time.
Die Verwendung von nichtrostendem Stahl zur Herstellung der Unterlagen an Stelle des gewöhnlichen Stahles verbietet sich wegen des hohen Preises des rostsicheren Materials. Derartige Bestecke würden teurer zu stehen kommen als solche mit Neusilberauflage.The use of stainless steel to manufacture the pads instead of the Ordinary steel is out of the question because of the high price of the rustproof material. Such cutlery would be more expensive than those with a nickel silver coating.
Bei den galvanisierten Bestecken aus gewöhnlichem Eisen oder Stahl gemäß der vorliegenden Erfindung ist dem geschilderten Übelstand dadurch abgeholfen, daß die Unterlage an den stark beanspruchten Stellen, beispielsweise an den Spitzen und den Aufliegestellenj aus rostsicherem Material besteht. Infolgedessen zeichnen sich diese Bestecke durch besondere Haltbarkeit aus und sind gleichzeitig billig herstellbar. Erfindungsgemäß ist es nämlich nicht mehr notwendig, den ganzen Besteckteil aus rostsicherem Material anzufertigen, sondern nur die gefährdeten Stellen, wodurch eine beträchtliche Ersparnis an teurem Material erzielt wird. Das Schweißen und Löten kann bei dem heutigen Stande der Technik auf billigstem mechanischem Wege erfolgen.In the case of the galvanized cutlery made of ordinary iron or steel according to The present invention is remedied the drawback outlined in that the pad in the heavily used areas, for example at the tips and the resting points consists of rustproof material. As a result, these cutlery are particularly durable and are at the same time cheap to manufacture. According to the invention, it is no longer necessary to make the entire cutlery from rustproof material, but only the endangered ones Places, whereby a considerable saving of expensive material is achieved. That With the current level of technology, welding and soldering can be done using the cheapest mechanical means Ways take place.
Als besonders geeignetes rostsicheres Material für den vorliegenden Zweck hat sich der rostsichere Stahl erwiesen.As a particularly suitable rust-proof material for the present purpose, the Proven rust-proof steel.
Einige Besteckteile gemäß der vorliegenden Erfindung und ihre Herstellung sind in den beiliegenden Zeichnungen beispielsweise veranschaulicht.Some items of cutlery according to the present invention and their manufacture are shown in FIG illustrated in the accompanying drawings, for example.
